True
Explanation:
In order to apply and experience the beauty of mathematics, a good comprehension of the discipline is required.
In fact, this is general to anything in life. To fully maximize any potential, one must be well groomed about what exactly that thing is.
Mathematics is a science that deals with the logic of shapes and numbers. There are different branches of this discipline with real world adoption.
The tenets of mathematics cuts across business, science, arts, e.t.c.

Answer:
While lifting two object the machine needs the different momentum for different mass object.
Explanation:
- Momentum is the quantity of motion contained in an object. Usually it is measured by the product of mass and velocity.
- Momentum of first mass = 2 kg × 2 m/sec = 4 kg m/sec
- Momentum of second mass = 4 kg × 3 m/sec = 12 kg m/sec
- So the machine requires higher mass in motion for second object ( i.e. momentum) than the first one while lifting.
Answer:
Gravitational force
Explanation:
If two spheres have equal densities and they are subject only to their mutual gravitational attraction. We need to say that the quantities that must have the same magnitude for both spheres. So, the correct option is (E) i.e. gravitational force.
It is because of Newton's third law of motion. It states that the force due to object 1 to object 2 is same as force due to object 2 to object 1. The two forces act in opposite direction.
Hence, the correct option is (E) "Gravitational force".
With the use of electric force formula, the direction and magnitude of the net force exerted on the point charge q3 are 9.9 x N and 66 degrees
ELECTRIC FORCE (F)
F =
Where K = 9 x N/
The distance between and can be calculated by using Pythagoras theorem.
d =
d = 46.7 cm = 0.467 m
For force , substitute all the parameters into the formula above
= (9 x x 3 x 1)/
= 2.7 x /0.218
= 1.24 x N
For force , substitute all the parameters into the formula above
= (9 x x 3 x 4)/
= 1.08 x /0.1089
= 9.92 x N
For force , substitute all the parameters into the formula above
= (9 x x 3 x 2)/
= 5.4 x /0.1089
= 4.96 x N
Summation of forces on Y component will be
= - Sin 45
= 9.92 x - 1.24 x Sin 45
= 9.04 x N
Summation of forces on X component will be
= - Cos 45
= 4.96 x - 1.24 x Sin 45
= 4.08 x N
Net Force =
Net force =
Net force = 9.9 x N
The direction will be
Tan ∅ = /
Tan ∅ = 9.04 x / 4.08 x
Tan ∅ = 2.216
∅ = (2.216)
∅ = 65.7 degrees
Therefore, the direction and magnitude of the net force exerted on the point charge q3 are 9.9 x N and 66 degrees approximately.

It's very hard to see the self-portrait, so I can't identify him.
